I am not debating the DOD satellite data, merely pointing out that the known
fall area, every piece I have heard of, fits a line from Olympia Fields to
Beecher. Hence the vise vera. That line goes NW-SE or SE-NW. I find it
interesting that an opposite trajectory angle has no confirmed recoveries
that I know of. Perhaps one of the Steves, Witt or Arnold IMB, can shed some
light on NE or SW recoveries. Any damage, any finds on a NE-SW line?

For those of you who are not familiar with the area, this will help. The
strewnfield based on reported finds and damage as I know it...NW/SE

I realize in my haste that I put "north" off to the left a bit when in fact
north is the top of the image.
Again I believe Paul Sipiera is making the master map, and I have not seen
it. While in PF a man named Tim Janecyk was doing nothing but coordinate
mapping with precise map markings that conformed the the linked rough
sketch.

I believe the satellite but where are the meteorites...and why? Even if the
near vertical drop constrained the fall, I see no remenants of the
documented trajectory in the fall pattern.

Very puzzled,
